data. How these differences affect saving in theoretical models depends on the metric one uses for risk. For labor-income …How does risk affect saving? Empirical work typically examines the effects of detectible differences in risk within the … risk, second-degree increases in risk require prudence to induce increased saving demand. However, prudence is not …

We show how optimal saving in a two-period model is affected when prudence and risk aversion of the underlying utility … function change. Increasing prudence alone will induce higher savings only if, for certain combinations of the interest rate … and the pure time discount rate, there is distributional neutrality between the two periods. Otherwise, changes of risk …

Using detailed tax data from the Swiss canton of Bern, I examine how changes in wealth are related to income risk. I … find that only among elderly individuals high kurtosis of income risk may be positively correlated with wealth accumulation … wealth investors experience sharp increases in wealth and income in subsequent periods. Finally, wealth risk is more …

We analyze optimal taxation of labor and capital income in a life-cycle framework with idiosyncratic income risk. We … independent of the social welfare function and determined by the degree of income risk and risk aversion. The optimal linear … provide a novel decomposition of labor income tax formulas into a redistribution and an insurance component. The latter is …

higher marriage rates and higher divorce rates will be associated with higher savings rates in the presence of economies of … marriage and with lower savings rates in the presence of diseconomies of marriage. In the context of traditional gender roles … traditional gender roles and marital status to understanding cross-country variation in gender differentials in savings behavior …

-probability extreme events on environmental policy in a continuous-time real options model with “tail risk”. In a nutshell, our results … indicate the importance of tail risk and call for foresighted pre-emptive climate policies …

The paper reexamines the welfare economics of intergenerational risk. Risk and its resolution over time are modeled as … preferences to (i) disentangle aversion to intergenerational inequality from aversion to risk, (ii) exhibit a preference for early … resolution of risk, (iii) show different discounting formulas depending on the magnitude of risk and on the timing of its …

assumption of (intertemporal) risk neutrality reduces the growth effect in social discounting and significantly amplifies the … importance of risk and correlation. Second, debate and models largely overlook the difference in attitude with respect to risk … and with respect to non-risk uncertainty. The paper derives the resulting changes of the risk-free and the stochastic …
